Insulated Concrete Walls

ABSTRACT

An insulated concrete wall includes a first form board, a second form board, a plurality of spacers, a plurality of rebar rods, a quantity of poured concrete and at least one insulation sheet. Each spacer includes at least one vertical passage for receiving a vertical rebar rod and a horizontal passage for receiving a horizontal rebar rod. The plurality of spacers are attached between the first and second form boards to create a concrete cavity. The quantity of concrete is poured into the cavity. The sheet of insulation may be attached to one or both form boards. The at least one insulated sheet may be replaced by an additional form board and the plurality of spacers. The additional form board would create an additional cavity, which would be filled with an insulation material. Alternatively, the two outer cavities may be filled with concrete and the center cavity filled with insulation.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to concrete walls and more specifically to an insulated concrete wall, which includes at least one layer of insulation.

2. Discussion of the Prior Art

Philippines utility model registration no. 2-2009-000170 to Taylor discloses a plastic wall stud spacer. Philippines design patent registration no. 3-2009-000287 to Taylor discloses a plastic wall stud spacer. Both the Taylor utility model no. 2-2009-000170 and the Taylor design patent registration no. 3-2009-000287 are hereby incorporated by reference in their entirety. However, the Taylor documents do not teach or suggest concrete walls with at least one layer of insulation or multiple concrete sections.

Accordingly, there is a clearly felt need in the art for insulated concrete walls, which include at least one layer of insulation multiple concrete sections.

SUMMARY OF THE INVENTION

The present invention provides insulated concrete walls, which include at least one layer of insulation section. The insulated concrete wall includes a first form board, a second form board, a plurality of spacers, a plurality of rebar rods, a quantity of poured concrete and at least one insulation sheet. Each spacer includes at least one vertical passage for receiving a vertical rebar rod and a horizontal passage for receiving a horizontal rebar rod. The plurality of spacers are attached between the first and second form boards to create a concrete cavity. The quantity of concrete is poured between the first and second form boards. A sheet of insulation is attached to the first form board, the second form board or both the first and second form boards. One side of a plurality of insulation spacers may be attached to either the first form board or the second form board. A third form board is attached to the opposing side of the plurality of insulation spacers to form an insulation cavity. The quantity of concrete is poured into the concrete cavity and the insulation cavity is filled an insulation material. The insulation cavity may also be formed on both sides of the concrete wall. An insulation cavity may also be formed between two concrete cavities.

Accordingly, it is an object of the present invention to provide insulated concrete walls, which include at least one layer of insulation or multiple concrete sections.

These and additional objects, advantages, features and benefits of the present invention will become apparent from the following specification.

The form boards 10, 12 are preferably James Hardie fiber cement boards, but other suitable form boards may also be used. Each spacer 14 includes at least one vertical passage 22 for receiving the vertical rebar rod 20 and a horizontal passage (not shown) for receiving the horizontal rebar rod 18. Each spacer 14 is preferably fabricated from a 100% recycled plastic material, but other materials may also be used.

The form boards 30, 32, 34 and 36 are preferably James Hardie fiber cement boards, but other suitable form boards may also be used. The first side of the plurality of spacers 14 are attached to an inside surface of the first form board 30 and the second side of the plurality of spacers 14 are attached to an inside surface of the second form board 32. The first side of the plurality of spacers 14 are also attached to an outside surface of the second form board 32 and the second side of the plurality of spacers 14 are attached to an inside surface of the third form board 34. The first side of the plurality of spacers 14 are further attached to an outside surface of the third form board 34 and the second side of the plurality of spacers 14 are attached to an inside surface of the fourth form board 36.
